How to choose the right power fiber laser cutting machine?

by FORSUN CNC mechanic

Industrial manufacturing in the new era puts forward new requirements for the accuracy, speed, and thickness of sheet metal cutting. The power that fiber laser cutting machines can reach is getting higher and higher. Many customers ask how to choose the power of the laser cutting machine when purchasing. Today FORSUN CNC will analyze how to choose the power of the laser metal cutting machine.

How to choose the right power fiber laser cutting machine?

First, select according to the processing material and cutting thickness

We choose the power according to the actual processing material and actual cutting thickness. So that we can determine which model to buy. For example, machine power, working area, etc., are a simple foreshadowing of later procurement work. The application fields of laser cutting machines involve multiple industries. Such as sheet metal processing, metal processing, advertising, craftsmanship, medical equipment, etc.

Laser has different effects on different metal materials. The laser power varies depending on the metal material. For example, under the same thickness, the laser power for cutting carbon steel is lower than that of stainless steel, and the laser power for cutting stainless steel is lower than that of yellow. Copper power is small. In addition to the properties of the metal itself, the thickness is also closely related to the laser power. For the same metal pipe, the cutting power of 10mm is lower than that of 20mm.

Secondly, choose according to the finish of the cut surface

Whether there are burrs on the laser cutting surface is mainly related to the cutting thickness and the gas used. There is no burr when cutting below 3mm. Nitrogen is the best gas, followed by oxygen, and the air is the worst. The metal laser cutting machine has few or no burrs, the cutting surface is very smooth, the speed is relatively fast, and the material deformation is relatively small.

Three, Selection of core components for laser cutting

The laser and laser head are imported or domestically produced. Imported lasers generally use IPG, and domestic lasers generally use Raycus. At the same time, pay attention to other parts of laser cutting, such as whether the motor is an imported servo motor, guide rail, bed, etc., because they affect the cutting accuracy of the machine to a certain extent.

Four, power selection

As for how to choose the right power, it should be decided according to factors such as the type, thickness, and shape of the material to be cut. Therefore, when purchasing a laser pipe cutting machine, be sure to let the manufacturer understand the characteristics of the material to be cut. The best way is to provide the pipe to the manufacturer for proofing.

There are many mainstream laser pipe cutting machines on the market, ranging from 1000W to 20000W. The thickness of the pipes of most manufacturers is between 8mm-12mm. If cutting this thickness for a long time, it is recommended to choose a 4000W-6000W laser pipe cutting machine. If it is brass with high reflection characteristics, it is recommended to use a laser pipe cutting machine with a power of 8000W or more. 2000W-4000W laser pipe cutting machine is recommended for the thickness of 5mm-8mm. A lower thickness of 1000W is usually sufficient. It should be noted that if you buy a 6000W laser pipe cutting machine, you can reduce the output magnification and adjust it to 2000W for cutting when cutting small thickness materials of about 4mm, which saves energy and saves electricity and costs.

Is the higher the power the better?

Is the power laser cutting machine good? Is the higher the power the better? It is a concern of many people. The mainstream trend of the market can always give users certain guidance, and the continuous appearance of Wanwa laser cutting machines seems to give users a hint: the higher the power, the better. Is this statement correct?

There is no doubt that competition in the field of fiber laser cutting machines has been fierce in recent years. In addition to competition in cutting technology, cutting speed, after-sales service, etc., laser cutting machine manufacturers have also made breakthroughs in higher power technology, vying to release 10,000-watt laser cutting machine products. However, there are still relatively few that actually use 10,000 watts of power to cut metal plates. To a large extent, manufacturers’ pursuit of a higher power is only a manifestation of technical capabilities. The higher the power, the more expensive the laser cutting machine. Power is one of the main factors that directly affect the price of laser cutting machines. High-power laser cutting machines require higher hardware requirements. The upgrade of the whole machine will make the cost of the whole machine skyrocket.

How to choose the right laser cutting machine?

Laser cutting machines can be divided into low, medium, and high power according to the power. For thinner stainless steel and carbon steel plates, a low-power fiber laser cutting machine can be used to cut very well, while ensuring a higher cutting speed, which not only ensures work efficiency but also saves costs. cost. Therefore, when choosing a laser cutting machine, you must make a reasonable choice based on your own material and the thickness of the material, and don’t blindly pursue high power. High-power laser cutting machines require higher hardware requirements. The upgrade of the whole machine will make the cost of the whole machine skyrocket. Therefore, when choosing the power of the equipment, we should consider the value we can accept.

Of course, if you have thick and thin plates for processing, and the production capacity is very large, a high-power laser cutting machine within the price range you can afford is also a better choice. Because by adjusting the cutting speed and appropriately changing the auxiliary gas, the high-power laser cutting machine can also control the cutting quality well.

Summary

Industrial manufacturing in the new era puts forward new requirements for the accuracy, speed, and thickness of sheet metal cutting. The power that fiber laser cutting machines can reach is getting higher and higher. Whether you are planning to buy a new fiber laser cutting machine, or have low-power equipment and are in operation, high-power laser equipment can bring you a better return on investment.
